Private disk management

The user sees only the reservation for the volume. The system manages the device needed to mount the volume. Devices cannot be reserved.

All reservation functions which result from DMS calls are interpreted as shareable reservation requests.

The SECURE-RESOURCE-ALLOCATION command permits shared or exclusive reservation of a private volume.

The control and supervision types for volumes can be set or modified with the aid of operator commands.

Device management offers automatic online supervision of the volumes used.

Volume supervision supports and monitors, amongst other things, the mounting of volumes and access to the volumes during file processing.
